The supervisory mechanism .herein illusm trated, described and claimedis particularly designed-to be employed "inconiiection with an indicatorpost or yard 'valve which controlsa sprinkler system located in anadjacentbuilding The indicator 'posta' is :trom the target screw "15. of'the-'target Screw is Aprovided with a rectangular socletivhich engageswith the up- F Aper end portion of the valve stem,`\vhich I 'the lugs orcomposed of tWo sections lO and 11 which telescope With each other anoare relatively adjustable. The section 10 is lined upon yand supportedby the valve' 12 which is to becontrolled by the device. Superimposedupon theupper section 11 is a cap 13 securedto Jthe section 11 by meansof bolts 14. Rotatably'mounted Within the cap 18 fis' a targetV screw'15 which lis Vheld from longitudinal movement by means ot theloch nut16 under the cap and the shoulder 16L mounted above the cap. There visprovided a wrench'meinber 17 which projects upwardly The lower end havedesignatedby the reference numeral .20. The lower end of this valve stem2O is provided With a socket member 21 which engages With-the upper endof a suitably shaped memberQQlconstituting' a part ot' the valve l2.VvIn.screw-threaded engagement with the target screw 15 is a. target nut2li'. This nu't'is providedwith one or more grooves in the side thereofwhich engage flanges- 26 on Vthey VVcasting 11. The. nut 24 may bemovedlongitudinally by turning the targetscreiv, but is prevented fromrotating-about its airis by the grooves and 'lugsv26t The target nut'has secured thereto a. plurality orp indicating' lor target platesyO,O,A and S, S adaptedv to be viewed through the --Wi'n'do\vs,Y VVtoindicate the condition of' the valve. It the valve is fully open thetargets O5 O, arevisib'le Whereas if thevalve is closed thefshut7targets S, S7 are visible;

Alln tot 'thei mechanism specifically describ'edfabove 'is 'oficonventional form and no claim is imade thereto except as lit forms -orconstitutes part# of" they combination through a slot-^30 in the castingl1v1 and 'als'.

Ythereto an arm 3G to which a watchmans hey, or other suitable manuallyoperable recording device 37, is secured by means of a flexible chain38. The casing 32 may be provided with a septum P, through which therock shaft 34 extends, to conceal and protect the main portion of themechanism.

The specific embodiment of the inventionn above described is designedVto operate as follows:

When the valve 12 is in normal position, in the present case fully open,the'parts occupy the position indicated in full lines in Figs. 1 and 2.A watchman in making his rounds may then obtain access to therecording'key 37, through the door I) of the ca sing 32, to produce apermanent record in his clock or other recorder indicating that thatparticular valve was normal (open) at that particular time. If howeverthe valve is in abnormal position, in the present case closed or evenpartially closed, the lrey is not available to produce a vrecord andVthis fact will appear on the Vrecord dial turned in by the watchman.

The operation by which the lfzey 37 is rendered inaccessible issubstantially as follows: Y Y f Y A few rotations of the member 17 inthe direction to close the valve cause the slide 33 to elevate to suchan extent as to cause the arm 36 to assume the position indicated indotted lines in Fig. 2, when the key is no longer accessible to producea record. When the arm 36 has reached the last mentionedposition thefiat face E ofthecam 35 is parallel to and in engagement with the andarm 36 are locked against rotation until the vvalve is restored tonormal condition. Continued rotation of the valve stein towardvalve-closed position simply Vcauses the slide 33 to travel .idly pastthe cam 35 so far as further actuation of the latter is concerned.`

tion of the system, the movement of the of the slide 33 and-thecammember.

slide 33 should be substantially parallel to that of the stud 29 and itsoperating members. In order to insure this condition and to facilitateproper assembly of the device the casing 32 is preferably provided witha rectilinearly movable element, means for Y simultaneously operatingsaid stem and ele-V ment, a cam having a flat portion associated withsaid elementto be engaged and operated thereby on initial movement ofsaid element in a predetermined direction and locked against movement onfurther movement of said element in the same direction, and a .recordingdevice controlled by saidv cam.

V2. In combination, a valve having a stem, Y,

a rectilinearly movable element, means for Vsimultaneously operatingsaid stem and element, a cam having a flat portion associated with saidelement to be engaged and operated thereby on initial movement of saidelement in a predetermined direction and locked against movement onfurther movement of said element inthe same direction, a rock shaft towhich said cam is secured, a manually operable recording device andmeans secured to said rock shaft for controlling said device.

3. In combination, a valve having'a rotal table stem, a rectilinearlyslidable element, means for simultaneously rotating said stem andoperating said element,g a cam engageable and operable by said element,a rock shaft to which said cam is operatively connected, a memberoperatively connectedto said shaft and spaced axially of said shaft Yfrom said cam, and a manuallyoperable recording device controlled bysaid last named 1-. Incoinbination, a valve having a rotatable stem, areetilinearly slidable element, Y means for simultaneously rotatingsaid-stein and operating said element, a cam engageable and operable bysaideleinent, a rock nected, an arm operatively connected to said shaftand spaced axially of said shaft from said cam, a watchmans lieyconnected to .shaft to which said cam is operatively con- 'Y said arm,and means for rendering said key inaccessible when said arm is in apredetermined position.

5. In combination, a valve Vhaving Va rotatable stem, a rectilinearlymovable element, means for simultaneously operating said stem andelement, a member mounted for movement about an axis and operable by andupon initial movement ofI said element in a predetermined direction andlocked against movement on further move ment of said element in the samedirection, and a recording device cont-rolled by said member.

6. In combination, a valve having a r0- tatable stem, a rectilinearlymovable element, means for Simultaneously operating Said stem andelement, a rock shaft, a member mounted on said rock shaft and operableby and upon initial movement of said element in a predetermineddirection and locked against movement on further movement of saidelement in the same direction, a manually operable recording device, andmeans secured to said rock shaft `for controlling said device.

7. The combination as set forth in claim 5 in which the recording deviceis a watclr mans time clock key.

8. The combination as setfortb in claim 6 in which the recording deviceis a Watchmans time clock key.

In testimony whereof I hereto aix my signature.
